The initially proposed system would have had a giant antenna consisting of 6,000 miles (9,700 km) of buried cables in a rectangular grid covering 22,500 square miles (58,000 km 2), two-fifths of the state of Wisconsin, [1] powered by 100 underground power plants in concrete bunkers.
Three electronic equipment shelters; two located near the perimeter of the site, and one at the base of the tower containing an antenna-tuning unit (ATU) UHF and LF receive antennas mounted on either a 10 ft. mast, 30 ft. light pole, or 60–150 ft. tower.
In radio communication, a ground dipole, [1] also referred to as an earth dipole antenna, transmission line antenna, [1] and in technical literature as a horizontal electric dipole (HED), [1] [2] [3] is a huge, specialized type of radio antenna that radiates extremely low frequency (ELF) electromagnetic waves.
For a 10-kiloton blast — equivalent to two-thirds of the Hiroshima bomb blast, or 5,000 Oklahoma City truck bombings — that's about a half-mile radius. But even in a 100-kiloton explosion, ...
The map will show the blast radius broken down into fireball, air blast and thermal radiation area. The program will calculate the number of casualties based on how many people live in the ...
A ground dipole antenna used for transmitting ELF waves, similar to the U.S. Navy Clam Lake antennas, showing how it works. It functions as a huge loop antenna , with the alternating current I from the transmitter P passing through an overhead transmission line, then deep in the earth from one ground connection G to the other, then through ...
But this only occurs within the severe blast radius for detonations below about 33,000 feet (10 km) altitude. [citation needed] During Operation Fishbowl, EMP disruptions were suffered aboard a KC-135 photographic aircraft flying 300 km (190 mi) from the 410 kt (1,700 TJ) detonations at 48 and 95 km (157,000 and 312,000 ft) burst altitudes.

The theft of a giant radio tower has silenced what used to be the voice of a small Alabama town and the surrounding county, the radio station's general manager said. A thief or thieves made off ...
